How does sulfur in coal change during gasification and liquefaction?

As the gasification process of coal is to burn a part of the coal in the air to form CO2 and H2O, then CO2 and H2O are reduced to CO and H2 (some of which are also CH4) by the unburned coal at high temperature, so the sulfur in the coal (Organic sulfur and pyrite sulfur) are also oxidized to SO2, but some pyrites react as follows:

FeS2+H2O→FeO+H2S+S

Organic sulfur in coal forms H2S; coal with high organic sulfur can also precipitate thiols, thioethers, and sulfonium and the like.

Sulfates (such as calcium sulfate) are reduced by hydrogen to CaS, ie

CaSO4+4H2→CaS+4H2O

The hydrogen liquefaction process of coal is essentially the reduction process of coal. Therefore, the sulfur in the coal is also reduced, that is, organic sulfur is almost converted into H2S. Pyrite can also act as a catalyst during the liquefaction of coal, accelerating liquefaction and reducing itself to H2S release. Therefore, during the hydrogenation and liquefaction of coal, almost all of the sulfur is reduced to H2S and consumed.
